3 Claims.

My invention relates to gliders ofthe swing type, and has for one of itsobjects the provision of a glider structure which, while it may beformed of metal members which are of light 5 Weight compared to thestructures of previous gliders, is nevertheless of sufficient strengthand rigidity.

Another object of my invention is to provide a glider structure whichcan be readily disassembled or knocked down, and which is of minimumoverall length.

One form which my invention may take is shown in the accompanyingdrawings wherein Figure l'is a face View of the glider; Fig. 2 is an endView thereof; Fig. 3 is an enlarged view taken on the line IIIIII ofFig. 2; Fig. 4 is an enlarged side view of a portion of the structure ofFig. 2; Fig. 5 is a view taken on the line V-V of Fig. 4; Fig. 6 isaview taken on the line VIVI of Fig. 2, and Fig. 7 is an enlarged faceview of aportion of the structure of Fig. 1.

The seat framework of the glider has at each end thereof, a yoke-likemember 9 having an arm rest portion I and depending front and rearleg-like portions H and I2, respectively. A rear seat bar I3 and a frontseat bar I4 have welded thereto at each end a bar I5, the bars I3, I4,and I being preferably in the form of angles. Box springs IE or othercushion-supporting elements are supported by the angles I3, I4, and I5.

Brace bars I! connect the leg elements II and I2 at each end of the seatstructure, the ends of the bars I? being laterally turned and welded tosaid leg elements. The use of these brace bars permits the yoke members9 to be made of lighter gage material than would otherwise be possible.The bars I'I also serve to prevent engagement of the cushions with thestationary end frames.

A back frame I8 has an angle bar I9 welded to its lower end, the bar I9extending the full length of the seat frame. A link member 2|, at eachend of the seat frame, has one of its ends pivotally connected to theback frame I8 and its other end pivotally connected to its associatedend bar I5. The bar I9 abuts against the rear sides of the links 2| andrearward tilting movement thereof is prevented, although it can befolded forwardly, when desired. The lower portions of the bars 2I seatagainst the upwardlyexposed faces of the bars I5. The pivotalconnections of the links 2I are, of course, removable, in order tofacilitate disassembling of the structure.

In order to provide for a firmer connection between the seat bars, Iprovide a yoke bar 23 at each end of the seat frame. The bars 23 arewelded to the leg members II and I2 and have their ends inwardly turned,such ends extending beneath the bars i5 and lying within the angles ofthe bars I3 and I4. The said inner ends carry pins or buttons 24 thathave interfitting engagement with key hole slots formed in the bars I3-I 4, as shown more clearly in Figs. 6 and 7.

The bars I5 and the pin and key hole connections referred to maintainthe parts in rigid relationship. In order to overcome danger ofaccidental disconnection of the pins 24 from the key hole slots, the bar23 may be slitted slightly to permit of tongues 24a being struck uptherefrom, and bent to the position shown in Fig. 7, between the ends ofthe bars I3 and I4 and the legs I2-I I, respectively. However, bydisengaging the key hole connections and disconnecting the links 2|, theseat frame structure can readily be knocked down for shipment orstorage.

The stationary portion of the structure includes a pair of end frameseach having a floor bar 26 that may suitably be provided with rubbercaps or pads 21; a pair of supporting bars 28 disposed in crossedrelation, and a top rail 29. Brace bars 3I are connected at each end tothe uprights 28. These bars may suitably be of angular form and have theheads of bolts 32 welded therein, the bolts extending beyond the ends ofthe bars, and through the uprights 28. When nuts are attached to thebolts, the end frames are thereby rigidly connected.

The lower ends of the crossed bars 28 are welded to the sides of thefloor bars 25, and their upper ends are welded within the groove orchannel portions of the top rails 29, and may be welded at their pointsof crossing. One bar 28 of each pair is offset somewhat, as shown moreclearly in Fig. 6, so that the ends of the uprights where they areconnected to the floor bars 26 and. to the top rails 29, will lie in acommon plane in each instance.

The seat frame is supported upon stationary end frames, at its fourcorners, by strap-like members 34 which are here shown as of springsteel; although these hanger members could be in the form of links.However, I prefer to use the spring strap hangers, because they permitof a smoother and noiseless swinging movement and resist any thrustswhich tend to produce end sway of the seat.

The upper ends of the straps are connected to the down-turned fiatportions of the top rails 29, by means of bolts 35. While the straps 34will ordinarily flex at various points throughout spring plates 37 beingemployed in the same 'manner as the spring plates 36.

It will be noted that the yoke members 9 of the seat frame arepositioned over and lie in the same planes as the stationary end frames.In order to prevent interference by these yoke members with swingingmovements of the seat frame,

the arm rest portions H! are made of considerably greater length thanthe leg portions and therefore are inclined downwardly toward oneanother, for connection to the lower ends of the verticallyextendingstraps 34.

Since the seat bars are inclined relative to the yoke-like member 9 andthe end frames, with a higher point of connection with the legelements Hthan with the legs [2, and the yoke members 9 are of light gaugematerial, stiffening strips 39 are welded to the rear sides of the frontlegs I l.

I claim as my invention:

1. A glider comprising a pair of stationary end frames each of whichincludes a top rail, a floor bar, a pair of substantially flat uprightsdisposed in relatively crossed relation and secured at their upper andlower ends to the top rail and the floor bar, respectively, one of theuprights being offset nel form and having down-turned ends, a floor bar,a pair of substantially flat uprights disposed in relatively crossedrelation and secured at their upper and lower ends to the toprail andthe floor bar, respectively, one of the uprights being offset to causetheir upper and lower ends to occupy a common vertical plane, suspendingelements connected to the ends of the top rails, andseat-supporting legsconnected to and extending upwardly from the lower ends of thesuspending elements, the legs, the toprail and the uprights, at each endof the glider, being disposed in a common vertical plane.

3. A glider comp-rising a pair of stationary end frames each of whichincludes a top rail, a floor bar, a pair of uprights secured at theirupper and lower ends to the top rail and the floor bar, respectively,suspending elements connected to the ends of the top rails,seat-supporting legs connected to and extending upwardly from the lowerends of the suspending elements, in relatively flared directions, and anarm rest carried by the upper ends of the legs, the legs, the arm rest,the top rail and the uprights, at each end of the glider, being disposedin a common vertical plane.
